Siemens 6ES5-267-8MA11 Stepper Motor Module IP 267

Siemens IP 267 Stepper Motor Controller, part number 6ES5-267-8MA11, is a dedicated SIMATIC S5 module that provides the control interface for a stepper motor driven through an external power section. It is designed to work with S5 CPUs such as CPU 102/103 in the S5‑100U family, and it uses a function block (FB 17) to support operator communication when paired with these CPUs. The front plate includes a 9‑way D connector for linking the motor power section to the IP 267 drive circuit, enabling the attached stepper motor to be powered by the external drive circuitry while the IP 267 handles command sequencing. LEDs on the front indicate status: a green RDY LED shows the module is ready, a green ACT LED pulses during active positioning, and a red ABT LED alerts to an interrupted positioning job. Before the IP 267 will accept positioning tasks, the controller requires a valid configuration frame from the PLC (defining parameters such as frequency range, start/stop rates, and acceleration/deceleration timing). The device’s role is to translate high‑level positioning commands from the PLC into precise step/direction signals for the connected motor drive, delivering deterministic motion control within the broader S5 system. The IP 267 module, catalogued under the Siemens 6ES5 series, is specifically the IP 267 Stepper Motor Controller variant 8MA11, and it is compatible with older Siemens S5 installations that rely on a modular stepper control approach rather than a standalone servo or DC drive.
